could alternatively be simulated by the equivalent current generator
in parallel with R (Sec. 12.1).
The tunnel diode oscillator is another example of an oscillator
circuit which requires only two connections to the resonant circuit.
14.9 Amplitude of Oscillation
So far it has been asumed that the amplifier or other negative-
resistance device used for maintaining oscillation was applied only
just sufficiently to make good the losses. This is quite an unpractical
condition, because the adjustment would be impossibly delicate in
the first place, and even if it could be achieved it would be upset by
the slightest change in temperature, componen ...
